Fig. 14, a detail of the mechanism for rotating the mast carrying frame.

In the present instance, I have illustrated the invention as embodied in a power driven road vehicle a of the tractor type, which is of known construction and is represented as a Steam operated vehicle provided with a body portion 12, supported by the rear wheels 0 and front wheels (Z, the latter being pivotally mounted to permit the vehicle to be guided over the road.

The tractor a is provided with a suitable motor 01' engine 6 for propelling it over the road and for performing one kind of work, and the particular type herein illustrated is designed for hauling material over the road.

The tractor a in accordance with this invention is provided with mechanism for performing work of a different character, and in the present instance, the tractor is shown in Fig. 1 as provided with mechanism which is capable of working on or above the surface of the road and, with slight changes, of working below the surface of the road.

I Referring to Fig. 1, 10 represents a boom, preferably made of two channel irons spaced apart and suitably secured together, (see Fig. 12). The boom 10 is provided with a track or guide 14 for a carriage or device 15, which is movable lengthwise of the boom on said track or guide, and is capable of being rendered fixed or stationary at any desired portion of the length of the boom or is capable of being freely movable lengthwise on said boom according to the kind of work to be performed, as will be described.

As shown in Fig. 1, the carriage 15 is stationary, being secured to the track or guide 14 by a pin 16. The boom 10 is pivoted at its inner end as at 17' to a carrier 18, which is movable lengthwise of a mast or support 19 normally vertically arranged.

The mast 19 is secured to a supporting frame, preferably made as herein shown and comprising bars or arms 20, 21, which are connected by a tie plate or bar 22.

In the present instance, the mast 19 is pivoted at its lower end as at 23 to the arm 20, and its upper end is secured to the arm 21, when the mast is to have a vertical position, and may and preferably will be adjustably secured to a curved extension 24 ofthe arm 21, when it is desired to have the mast given different inclined positions. The curved extension 24 is preferably pivotally secured to the arm 21 by a hinge 25 or otherwise, which permits the extension to be folded or turned back so as to rest on the arm 21 when not in use. The extension 24 may be provided with suitable holes '26 spaced apart to enable the upper end of the mast to be secured in fixed relation to the extension by a suitable pin 27, and thereby render the mast stationary in different inclined positions. The extension 24 is made in a curve having the pivot 23 as a center, and is also preferably made as a channel bar, and the mast 19 is preferably provided with a roller 28, which is movable in the channel of the extension, and to avoid the necessity of machining the channel bar extension, the mast 19 is provided with a movable upper member 30, which carries the roller 28 and is acted upon by a spring 31 to hold the roller 28 in engagement with the upper or outer flange of the channel bar. The arms 20, 21 of the supporting frame are provided with collars or eyes 32, 33, through which are passed a rotatable shaft 34 having a bearing in a sleeve 35, which is mounted in a stationary frame or support attached to the body portion 6 of the road vehicle.

In the present instance, the stationary frame comprises a spit hub 36 having arms 37, which are riveted or otherwise fastened to the body portion 5 of the vehicle, and said split hub receives the bushing or sleeve 35, which is clamped between the members of the split hub, by a bolt 38 extended through suitable cars 39 on the members of said hub. The arms 20, 21, of the mast supporting frame are keyed or otherwise fastened to the shaft 34 so as to rotate therewith, and said shaft is provided with a worm gear 40, which may be driven as herein represented by an auxiliary engine or motor 41 suported by the body portion 7) of the vehicle or said shaft may be other wise rotated. The rotatable shaft 34 is conconfined against longitudinal movement by collars 42, 43, fast thereon.

In the present instance the worm is driven by a worm 44 on a shaft 45 (see Figs. 1 and 14) provided with a pulley 46, which is connected by a belt 47 with a pulley 48 on the shaft 49 of the engine or motor 41. which latter is of the reversible type.

The boom 10 carries a bucket or scoop 50, which may be closed at its bottom, back and sides and open at its front end and provided with suitableteeth 51, and said bucket may be stationary or movable with relation to the boom, and may be arranged on the latter so that its front end is presented toward the front end of the boom or toward the rear end thereof, according to the kind of work to be performed. In Fig. 1, the bucket 50 is arranged with its open end toward the front end of the boom, and is movable longitudinally thereon, and when so arranged, the apparatus is adapted for work on or above the surface, the bucket being loaded on its forward movement from the rear of the boom toward the front thereof.

The forward movement of the bucket is eflected by a cable or like device 52, which has one end fastened to the bucket and is passed'over a guide roller 53 carried by the tially: parallel with the boom, by takingiu p 1=,-3 teeter boom in-front thereof and under a. guide ro1ler'5 t-carried by the mast 19; andivvound.

upon a drum. 55- (seeFigs. 9. andlO) supported: by the body portion b. of the vehicle nearthe front thereof.

Thebucket is guided in its movement lengthwise of. the boomv by suitable means herein. shown as arms 56 attached to=the oppositesides of the bucket and extended upwardly-om opposite sides of the boom, said arms being connected by a rod 57,- which is designed to engage the underside of the boomiand keep-the bottom of the bucketparallel: with the boom.

Provision is also: made for automatically locking the bucket. in its dumping position, while permittingthe bucket to move-lengthwise of the boom and also to moveinto its dumpingposition.

In the present instance, I have. shown: oneform or construction ofiautomatic look, (see Figs. I and 1=3)-,.which|-consistsi of elliptical blocks or: cams 59 fast onarms 60 fastened to the-opposite sides of thebucket, saidcams being located in.sockets of. correspondingshapeand each of which is formed by recesses- GI, 62', in bars. 63', 6.41 forming. trucks, which are-located ineach. side channel or guidewayr65 in the boom L0;

The bars 63, .649, .are provided. with rollers 66', which are designedito. engage the' top and bottom flanges .of,eachi guideway or channel165 in: the-boom, and said rollers are designed to be pressed in .sufhciently' firm engagement with the said flangesto hold the trucksstationary, by then-cams 59iforcing apart the members or barsa63, 64;, of the tIl1Cl(',.=Wh611':fil18 bucket; is.v turned. into its: dumpingposition.

The-winding drums 55, '75, are normally loose on the shaft 'Z6a1idiare adapted to be rendered fast thereon by clutches 78, 79;. of

any suitableconstruction and which are controlled' as hereiirrepresented by suitable levers 80; 81, (see Fig. 10) The winding drums 55, 75 may be held stationary by band. brakes 82, 88 controlled by! levers 845,-.

85,. inamanner Well understoodi The drum shaft 76 is operativelyconnected with the motor or engine 6 employed tQJPllO pol the: vehicle, which-may be effected. in any suitable manner, as for instance las shown in Figs...1 9;-10, 11, wherein: the drum shaft 76: is. shown? as PIOViClBClEWl'Gh gears-:86;- whichmesh .withzpiniions 871 on-a-countershaft 88;

Fig. 11.. they r are. out .ofmesh; with the gears 95, 96,-an'dr the vehicle isat rest while the engine continues'to. run] The. shaft 921s driven fnonrthe crankshaft 89% by the gears .94.. 9.3-, and; the-shaft 92 is geared to the shaft 99 by: thegears 101, 102-, the latter being normally loose on theshaft 99fL1TCli adapted to" be rendered fastthereon by arclaltch of any suitable construction, whichwis conventionally represented as a member 103 fast to the gear 102 and a mem- 1 3 0 her 104 mounted on the shaft 99 to rotate therewith and to slide thereon. The clutch member 104 may be moved by a shipper or clutch rod 105 or in any other suitable manner. By means of the clutch 103, 104, the vehicle a may be propelled without neces sitating stopping of the engine to shift the gears 97 98. The crankshaft 89 is provided with a pulley 106, which is normally loose thereon and adapted to be rendered fast to said shaft by a clutch member 107 coiiperating with a clutch member 108. The pulley 106 is connected by the belt 90 with a pullev 109 on the shaft 88.

\Nith the arrangement shown in Fig. 1, the bucket 50 may be moved from the rear to the front of the boom 10 so as to pick up its load from the surface of the road, by throwing in the clutch member 107 so as to rotate the drum shaft 7 6, and by operating the clutch lever 80 so as to render the winding drum 55 fast on its shaft 76 and effect winding of the cable 52 upon the drum 55. When the bucket has been loaded, the drum 55 is held by the brake band 82, and the clutch lever 81 is operated to wind up the cable 70 and elevate the boom, as for instance, into the position shown in Fig. 2.

hen the bucket has been elevated, the shaft 34 is rotated so as to move the mast supporting frame to the right or left and thereby bring the loaded bucket into the desired position for dumping.

The movement of the shaft 84 is effected by manipulating the reversible engine 41 according to whether the bucket is to discharge its load on the right or left side of the tractor or vehicle a.

To dump the load in the bucket, it is only necessary for the operator to release the brake 82 on the drum 55 and allow the cable 52 to be paid out, which permits the bucket to turn on the cams 59 as a pivot and assume a substantially vertical position over the receptacle into which it is desired to discharge the load. When the bucket is in its dumping position, it is automatically locked on the boom and prevented from running down thereon, by the action of the cams 59 as above explained.

After the bucket has discharged its load, the drum 55 is rendered fast on its shaft 76 to take up the slack in the cable 52 and bring the bucket back into its operative position' substantially parallel with the boom.

The apparatus as represented in Fig. l is adapted for excavating or surface work, but the construction is such, that the apparatus may be converted in a minimum time into an apparatus for other kinds of work as will now be described.

In Figs. 3 and 4, I have shown the apparatus as arranged for trench work, for which purpose, the bucket 50 shown in Fig.

1 is used but is reversed on the boom, that is, its front or cutting edge is arranged to move toward the mast 19 when taking its load, and the rear end of the bucket is connected by a cable, rope or the like 110 with the carriage 15, which is made movable on the track 14 by removing the fastening pin 16. In this case, the bucket is located near the outer end of the boom when in its starting position and is moved toward the rear end of said boom when taking its load.

The bucket 50 is moved so as to take its load by winding the cable 52 on the drum 55, which cable in this case is attached to the front of the bucket, and on this movement of the bucket, the carriage 15 is moved on the track 14 toward the front end of the boom, the cable 70 being paid out to permit of this movement of the carriage. WVhen the bucket is loaded, the cable 70 is wound up on its drum 75 until thecarriage 15 meets a stop or block 112 which is fastened to the track 14. The loaded bucket is thus brought back to near the front end of the boom, which is then lifted by winding up the cable 7 0 until the bucket has been removed from the trench, whereupon the shaft 34 is rotated so as to bring the bucket into dumping position, whereupon the cable 70 is held and the cable 52 slackened to permit the bucket to be turned by gravity into its dumpin position, in which it is automatically loc ed as described with reference to Fig. 1.

When used in trench work, the pivot carrier 18 for the boom is moved up on the mast 19 by a hand line 113 and is secured in its adjusted position thereon by means of bolts or screws 130 or otherwise, and by adjusting said member on said mast, the boom may be given difierent angular positions, according to the angle on which it is desired the bucket should out.

In Fig. 4, the pivot carrier 18 is shown as adjusted on the mast 19 with the latter in its vertical position, and the boom is capable of being lowered into a trench to have the bucket cut the earth at one angle, and by raising or lowering the pivot carrier 18 on the mast 19, the angular position of the boom with relation to the mast may be changed to vary the cut made by the bucket. It is also highly desirable to be able to make a substantially vertical cut in the trench, as for instance, to form an end wall therein, and for this purpose, the mast 19 is made adjustable from a substantially vertical position into different angular positions, which is accomplished as herein shown by providing the mast supporting frame with the extension 24. When the mast 19 has its free or upper end secured in fixed relation to the extension 24, as for instance, as represented in Fig. 3, it will be seen that the boom 10 assumes a substantially vertical position, and that the bucket when moved upward will make a substantially vertical cut. The features of the pivot carrier 18 for the boom being adjustable on the mast, and the latter capable of adjustment into an inclined position, may be advantageously employed with a bucket which does not travel lengthwise of the boom, but is located near the frontend thereof, as represented in Fig. 5, and is capable of being moved in the arc of a circle with the pivotal attachment 115 of the bucket to the boom as a center.

When the parts are arranged as shown in Fig. 5, the bucket makes a circular cut, and may be advantageously used for side hill or trench cutting and in other places where crowded motion is required, which latter is obtained by moving the vehicle forward.

The feature of the pivot carrier 18 for the boom being adjustable lengthwise of the mast, enables the apparatus to be used for other purposes than digging or cutting work, and further permits other forms of buckets to be used for different purposes.

This is illustrated by Figs. 6, 7 and 8. In Fig. 6, the pivot carrier 18 is located at the bottom of the mast, and the bucket 50 is of the ordinary kind for holding materials.

The arrangement shown in Fig.6 can be used to advantage for handling materials employed in making concrete, such as the aggregate, for in this case the boom can be manipulated so as to place the bucket above the pile of aggregate and then lowered to the ground to be filled, after which" the loaded bucket is raised and theboom swung around to the concrete mixer, into which the load in the bucket may be dumped.

In this manner, the materials -may be handled with a minimum expense, time and labor.

In Fig. 7, the pivot carrier 18' is adjusted into an elevated position and the boom is raised into a horizontal position, and the bucket 50 used is shown as of the clam-shell type, which can be loaded and unloaded by manipulating the friction drums 55, 75, and

which can be swung from its loading position into its unloading position, etc. With the apparatus adjusted as shown in Fig. 7, a different tool or device other than a bucket may be used for hoisting other objects, similar to a derrick.

In Fig. 8, the pivot carrier 18 is shown as adjusted into a different position on the mast from that shown in Figs. 6 or 7, and a different type of bucket used, which is movable lengthwise on the boom and into which ag regate or other material can be shoveled when the bucket is near the rear of the boom and then moved to the front end of the boom, and swung around until it is over drums.

the hopper of the concrete mixer, and then vdumpec.

It will be understoodythat the mast,'boom, etc'., shown in Figs. 6, 7 and 8, are used on the tractor or road vehicle shown in Fig. 1, and are shown-to illustrate the scope and usefulness of a tractor, road roller or like vehicle embodying this invention.

Byreference to Fig. 1, it will be observed that the mast is not rotated on its own ax-is but'is carried by a frame which rotates with a shaft supported by a frame or device fastened directly tothe body portion of the vehicle, and as a result, the endthrust is transmitted to and is taken care of by the body portion of the vehicle, which is of sufficient strength to do so.

' I have herein illustrated one form of road vehicle, but it is not'desired to limit the invention inthis respect.
